JOHN G. HENDRIOKSON, OF PHILADELPHIA, PENNSYLVANIA.

COMBINED REGISTER BACKING AND DAMPER.

Specification of Letters Patent.

' Patented April 7, 1908.

Application filed February 16, 1907. Serial No. 357,781.

To all whom it may concern:

Be it known that 1, JOHN C. HENDRICK- soN, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Combined Register Backingand Damper, of which the following is a specification.

My invention relates to a new and usefulcombined register backing anddamper and consists in providing side plates for the register framewhich conform to the sizes of the hot air flues in which they are to besituated 210 that they do not obstruct the said hot air It furtherconsists in pivotally mounting a flue damper in said sides.

It further consists in providing means adapted to pass throu h the faceof the register for actuating sai flue damper.

It further consists of novel details of constuction all as will behereinafter fully set forth.

Figure 1 represents a perspective view of a combined register backingand damper embodyin my invention. Fig. 2 represents a vertica sectionalview thereof, showing the device in position. Fi 3 represents a rearelevation showing the evice when used in a hot air flue Wider than theregister backing.

Similar numerals of reference indicate correslponding parts in thefigures.

eferring to the draw1ngs:in the present construction of registers theframe of the register is su ported by the wall and the damper for t eflue is'mounted above the register with the means for actuating the sameprojecting through the wall in which is usually placed a cu where theactuating means projects. I ave found in ractice that in order toinstall registers considerable time is expended in placing the sameproperly in osition, that the p aster sometimes accumuIates to too greatan extent in the flues and in some cases, the frame falls into the fluewith consequent ill results. In addition, where the dampers are lacedabove the register in the flue, shoul the damper become broken ordisarranged, it is necessary in nearly every instance, to break theplaster and paper in order to replace the said damper. My invention isdesigned to overcome these difficulties and by reason of placing theflue damper in the backing which is suitably connected with the registerframe the entire de-.

vice can be removed from its position in the wall without destroying thelatter or the paper and can be quickly replaced in position without fearof its falling into the flue.

In the drawings I have shown a construction for carryin out my inventionbut it will be evident t at the arrangement of the parts may be variedand other instrumentalities used, which will accomplish the same resultsand I do not, therefore desire to be limited to the construction asherein shown and described.

1 designates the register frame of any de sired construction to which ismovably attached the front plate 2 thereof, said plate being adapted tobe secured to said frame in any manner, preferably by screws, and saidframe being provided with the register dampers 3 which are preferablypivotally mounted therein, in any desired manner and which can beactuated by the pin 4, projecting beyond the face of the register in anydesired manner, it being understood that in one position the dampers 3open the register alowing the passage of hot air into the room and in,the other position'entirely close off the register.

Connected in any desired manner with the frame 2 is the backing 5 whichcan be made of any desired material, as for example galvanized iron,said backing being preferably formed of substantially the shape and sizeof the register frame in order to frlctionally engage the sameiwherebyit is supported. Projecting from the backing 5 are sldes, of wings 6which extend from the backing, a distance equal to the width of the hotair flue in which they are to be situated, whereby it will be seen thatwhen the parts are laced in position the backing and register frame areheld in flue. Pivota y mounted in the sides or wings 6 is the fluedamper 7 which in the present instance is provided with the pins 8,projecting beyond each side thereof which are adapted to enter suitableopenings in the sides 6 which latter are inwardly curved at 9, in orderto receive the said pins and the damper 7 is suitably cut away as at 10in order to provide for the inwardly projecting portions 9 of the sides.The said damper 7 1s preferably made with the angular extension 11 whichis adapted, when the. damper position and prevented from falling intothe is in closed position to sufficiently overlap the upper ortlon ofthe backing to prevent assage 0 the hot air while the lower end 0 thedamper is adapted to contact with the walls of the flue in order toprevent passage of hot air at this point.

I preferably form the backing register frame of the size to correspondwith the width of the hot air flue but in some instances the said fluemay be somewhat larger than the register frame and backing and in orderto meet this difficulty I provide the extensions 12 on the sides whichextentions can be bent outwardly as seen in dotted lines in Fig. 3 inorder to contact against the sides of the hot air flue and preventpassage of the hot air between the sides or wings and the sides of thehot air flue.

Pivotally connected with the damper 7 is the rod 13 which in the presentinstance is connected above the pivotal point of the damper and projectsoutwardly and through an o eningll l in the register face and is pro-'vide wit a threaded end on which is mounted the knob or handle 15 forease in o eratin said rod. By pulling the said rod t e flue amper willbe opened and by ushing in the same the damper will be c osed. Bythis'means it will be seen that I rovide a register having the usualdampers 'or closing the openin thereof and with a backing which carriest e flue damper so that all of the parts can be removed at one time andinserted in position. Also mounted upon the rod 13 is a stop nut 16which can be adjusted upon the threaded end of the rod 1.3, in order tolimit the throw of the damper 7.

From the above it will be seen that I pro vide a combined backing anddamper for registers, the backing being adapted to fit the flue, so thatwhen the register is placed in position the walls of the backing contactwith the walls of the flue to prevent the register from falling into theflue and at the same time I provide a support for the flue damper,whereby the same can be removed with the register. Any means forconnecting the ends of the backing may be employed an d in the drawingsI have shown a pin 17. In cases where the backing fits the flue, theflanges or extensions 12 can be cut off at a point indicated by dottedlines in Fig. 2 or the can remain as shown in Fig. 2.

aving thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
